### **Descriptions:**  
The MAX4081FAUA is a precision, high-side current-sense amplifier designed for applications requiring monitoring of current in high-voltage systems. It features a wide input common-mode voltage range (up to 76V) and provides a fixed gain for accurate current measurement. The device operates with a single supply voltage and offers rail-to-rail output swing for compatibility with low-voltage ADCs or microcontrollers.  

### **Features:**  
- **High-Side Current Sensing:** Eliminates the need for low-side sensing.  
- **Wide Input Voltage Range:** Supports up to 76V common-mode voltage.  
- **Fixed Gain Options:** Available in 20V/V, 50V/V, or 100V/V.  
- **Low Quiescent Current:** 500µA typical for power efficiency.  
- **Rail-to-Rail Output:** Ensures maximum dynamic range.  
- **High Accuracy:** ±1% maximum gain error.  
- **Compact Package:** 8-pin µMAX for space-constrained applications.  
- **Wide Temperature Range:** Operates from -40°C to +125°C.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
